I Letters Patent No'. 106,363, dated .Augztl6JlQL- IMPROVEMENT IN' LAME-BURNERS.

The Schedule referred to in these Letters Patent and making part of the sar/1e ,To all whom it may concern Be it known that I, HIRAM W. HAYDEN, ct Waterbury, in the county of New Haven and VState of Connecticut, have invented,f and made an Improvement in Lamp-Burners;V and the following is declared to be a correct description't-hereo Before this invention, a lam p-buruer had been made with a circular wick-tube and an interior air-tube, the two being connected on one side, and the wick passing at cach side ot' this connection, so `as to form an Argand lamp. This character of lamp may be seen in Webster 8L Parkls Encyclopedia of Domestic Economy, page 190. g

This invention of mine is intended to facilitate the construction ofthe burner, lessen its expense, and insure the iaising and lowering of the wick wit-h uniformity. Y

' I make use of a tapering exterior wick-tnbe'and a nearly cylindrical interior air-tube, and provide an opening for the lateral admission of air to the airtube, and I provide a wick-holder and slide, 'operated by a rack and wheel, so as to raise or lower the Wickr with accuracy, and a movable chimney-holder is provided around the wick-tube, and. above a perforated air-distributer.

By this construction thewick can be entered with facility between the tubes, vwhen the wick-holder is moved tothe upper end ofthe wick-tube, and the wick is drawn through .a suitable distance, so that,

when The wick and raiser are drawn down by the actuating-wheel, the top of the wick can be trimmed, and raised or lowered, to regulate the light; and,` as the length of wickis burnt up, thesamc can be drawn further ont from the holder. until the wick is consinned.

In the drawinga is the exterior wick-tube, of a circular but slightly tapering form,`a11d connected to the same is the screw or ring b, by which the burner is tobe attached to the reservoir.

c is a perforated or foramiuous airdistributer, ot` suitable size and shape, surrounding the tube a, and upon which the chimney-holder d rests or is attached.

Within the' tube e is the central air-tube e, that is of a cylindrical forni, so that there will beaproper space left atj the upper ends ot' the tubes a and c, for the wick, which wick is of a dat form, bent into a cylinder atthe upper end of the burner, to produce an y Argand dame.

The interior draught is admitted laterally into the air-tube e by au opening and tubular connection, at f, Ibetween the tubes a and e.

The wick-holder iis made Aas a band, partially or entirely surrounding the wick, with projecting points, to penetrate the wick, and connect therewith and from one side of this wick-holder ta rack-bar, Lpasses down inside the tube n., to the wheel h, so as to 'form a rack and pinion to operate thewick-holder. I find that a convenient way of making this rack and pinion is to provide arow ot' holes'in the rack, and -use pointed pinion-teeth.

The rack is to be guided by passing through a slide,.m.

A thumb-wheel, 7c, upon the shaft of the pinion h, l

is employed for actuating the same.

It will now be understood that, when the wickholder is moved to the top of the burner, the wick can be slipped or pushed up from below, and drawn evenly through within this holder t the proper distance, and that this holder willoperate to lower or raise the wick with uniformity, and, when consumed down to -the wick-holder, the wick can be .drawn through another length, as before.- By thisl means the wick will be operated more uniformly than with the screw wick-raiser heretofore used on Argand lamps. V A

rI'he chimney-holder is shown as formed of arange of clamping-springs, n, connected with a tapering perforated gu'ide,o, that surrounds the wick-tube a, and is within the chimney t, so that. the holder, chimney, -and guide o ca'u be liftedol' the burner to give access to the wick, and, when the chimney-holder and guide are in place, the air, passing through the distributor c, is divided, a portion going` into the air-tube e, and the remainder passing through holes in guide o,`to supply the externalrdraught to the-llame. f

Figure l is a vertical section of my improved burner, and' Figure 2 is a similar view at right angles to fig. l.

I claim as my invention- V -l. The wick-tube a, interior air-tube e, .and lateral connection f, in combination with the Vwick-holder i, rack-bar l, and wheel h,substautially as and` for the purposes set forth.

2. rIhe tapering perforated guide o and spring chimney-holder n, constructed ,-substantiallyas specitied, and combined wit-l1 the-forainino'us air-distributer. c, that supports the removable spring chimney-holder and guide when in place, substantially as set forth.

Signed by me this 25th day of June, A. D. 1870.
